Uh, wow. Just...wow. It looks like they used the ends of a full-floater Dana 60 and welded the drums or something onto the hubs, then used only 3 lug nuts to "secure" the wheel...
The hood looks to be there and the tin looks in decent shape apart from the damaged corner. This is one of the times where I'm tempted to say the mechanical aspects of the tractor are much worse than the cosmetics.
Honestly, unless I wanted something from it for another machine, or it was so stupidly cheap (a couple hundred dollars) that I couldn't help myself, this is one of the few I'd pass on. The things that seem wrong are all expensive and complex (Transmission, front axle and drive mechanism) to repair. On top of that, the front end situation is just unsafe to me, and I do all kinds of stupid stuff. I wouldn't want to sell it, because I think it's unsafe. I for sure wouldn't use it to replace another machine like your 226D, which I really liked using and worked well.
The loader looks to be a good one, and the engine has some value. Otherwise, I honestly suspect you'll be money ahead to avoid repairing the front end properly and just buy one in reasonable condition to start with. It is almost certainly worth some profit parted out; I just hate dealing with individual items and that many buyers.
The troubles I see with the tractor are not the deferred maintenance or neglect sort of problems I love to see when I'm looking for a bargain. These are deliberately abusive, unsafe woes. Nobody accidentally, negligently, or lazily scabs outers from a fullsized American truck onto the front of a Japanese tractor. That level of ambition to me either means they are competent and know what they are doing (In which case the 4 wheel drive would work, the shifter, which is really a mega-strength of the Powershift machines, would be easy to use, it would drive, etc), or else they are such knuckleheads that they don't even know what they are doing is stupid and unsafe, so create hazards where none need be, and endanger all future operators of the machine, in addition to fouling up their own equipment unnecessarily. I don't think this work was done with wisdom, obviously, which leaves only bad alternatives.
If you buy it, I hope it works out well for you. Domush did a fine job getting his abused 336D back in working order, so it certainly can be done with enough time, determination and money.
